Google Classroom rolled out a few updates this summer and I am sharing two of my favorites. They are both simple, but very helpful. If you have multiple classes you can drag and drop to reorder or organize the order they appear on your Google Classroom homepage.
Secondly, when sharing the code with students so they can join your Google Classroom it can now be displayed much larger and viewed from the back of the classroom. Press the down arrow near the class code and then select display.
